Check your domain

Published: 2026-07-22 · Updated: 2026-07-23

Just added an MX record and want to know whether it worked? Paste either the whole address or just the domain — name@example.com and example.com give the same answer. This page tells you where that domain's mail actually goes, and whether you can already pick it here when you generate an address.

It also works for any other domain — handy when a sign-up form rejects an address and you want to see whether the domain receives mail at all. Setting up your own domain is described step by step in New Email Generator domain name.

How to read the answer

Whatever you check, the result is one of these:

✅

The MX points here. Mail for the domain reaches our server. Once the domain also shows up in the pool, you can pick it in the drop-down and use any name in front of the @.

⚠️

Our server is there, but not first. Mail goes to the record with the lowest priority number, so a second record with a smaller number takes everything. Ours has to be the smallest, or the only one.

⚠️

Two records share the lowest number. Then the sending server picks whichever it likes, and mail arrives only some of the time — the kind of fault that looks random for weeks. Leave one record at the lowest priority.

💡

The MX points somewhere else. That is the normal answer for any domain you do not own — Gmail, a company domain, a shop. Mail goes to that provider, not to us, and nothing here can read it.

⚠️

No MX record at all. Nobody receives mail for that domain. A letter sent to any address on it bounces — this is worth knowing before you write to an address someone gave you.

Just added the record and it still says no?

Almost always it is one of these, in order of how often they happen:

DNS has not spread yet. Registrars promise minutes, reality is anywhere from a minute to a full day. This is the boring answer and the most common one — check again later before changing anything.
The trailing dot. Many control panels want the target written as generator.email. — with a dot at the end. Without it some panels quietly append your own domain and the record ends up pointing at a host that does not exist.
The record sits on a sub-domain. The Name / Host field should be empty or @. If it says mail, you have created an MX for mail.your-domain.com, and the domain itself still has none.
An old MX is still there. Parked domains often come with the registrar's own MX record. Two records mean mail can land in either place — delete the one you do not need.
A CNAME on the same name. If the root of the domain is a CNAME, DNS rules say other records on that name are ignored. Replace it with an A record and the MX starts working.

What this page does not check is SPF, DKIM or DMARC. Those matter for sending mail; for receiving — which is all you need here — an MX record is enough on its own.

🔎

MX looks right and letters still do not arrive? The next suspect is the domain's reputation — a name on a spam blocklist gets its mail dropped silently. Check the domain against the blocklists, and see SPF, DMARC and DKIM in the same place.
